Hi all,
I'm moving to a new web server and struggling to get it configured properly. The problem of the moment: having a Perl CGI script call another web page in the background and make decisions based on its content. On the old server I used an antique Perl script called "hcat" (from the Pelican book<http://oreilly.com/openbook/webclient/ch04.html>); I've also tried curl and LWP::Simple.
In all three cases, I get the same behavior: it works just fine on the command line, but when called by the web server through a CGI script, the LWP (or other socket connection) gets no results. It sounds like a permissions thing, but I don't know what kind of permissions setting to tinker with. In the test script below, my command line outputs:
Content-type: text/plain
Getting URL: http://www.npr.org
885 lines
Whereas the web output just says "Getting URL: http://www.npr.org" - and doesn't even get to the "Couldn't get" error message.
Any clue how I can make use of a web page's contents from w/in a CGI script? (The actual application has to do with exporting data from our catalog, but I need to work out the basic mechanism first.)
Here's the script I'm using.
#!/bin/perl
use LWP::Simple;
print "Content-type: text/plain\n\n";
my $url = "http://www.npr.org";
print "Getting URL: $url\n";
my $content = get $url;
die "Couldn't get $url" unless defined $content;
@lines = split (/\n/, $content);
foreach (@lines) { $i++; }
print "\n\n$i lines\n\n";
Any ideas?
Thanks
Ken
